Look at the way the accent is viewed in in the wider society- is it accepted or is it regarded as "substandard" or "nonstandard". For example, in British English, Cockney and Estuary are related- Estuary takes many features of pronun ciation from cockney and can be seen in educated speakers. Tony Bliar has adopted many of its features (glottal stops) since he became prime minister, while Cockney remains associated with working class speakers in particular parts of London, and is less accepted among the more conservative and traditional areas od society.
